If the number of ports present on the SoC/board is not the maximum
and that the platform data is not filled with all data, there is
an easy way to mess the PIO setup for this interface.
This quick fix addresses mis-configuration in USB host platform data
that is common in at91 boards since commit 0ee6d1e (USB: ohci-at91:
change maximum number of ports) that did not modified the associatd
board files.

Alan, Greg, gentle ping...
I really would like to seen it landing in stable soon...
Thanks, best regards,

Sorry for the delay. I feel a little uncomfortable judging board-level
changes like this, since I know nothing about the hardware details.
Still, for what it's worth, this patch is okay as far as the core
ohci-hcd driver components are concerned. So...
